摘　　要：采用有限元数值计算方法,对一出现基础不均匀沉降及支柱倾斜的液化石油气球罐进行了应力计算,分析了基础不均匀沉降和倾斜对球罐应力的影响。结果表明,出现基础不均匀沉降和支柱倾斜后,球壳应力变化不大,但在支柱上产生了较大的附加应力,附加应力的大小主要由基础不均匀沉降差决定,而倾斜产生的附加应力较小。基础的不均匀沉降差对支柱的应力影响很大,是影响球罐安全的主要因素。The stress of a liquefied petroleum gas spherical tank with pillar slanted on differential settled ground was calculated and analyzed by finite element method. The results show that the slanting of pillars produced a less affect on the stress of the shell and pillars, while the differential settlement produced a greater impact on the stress of pillars. The differential settlement is the key factors affecting the safety of the spherical tank.
